[a]For high-strength bolts subjected to tensile fatigue loading, see Appendix 3. [b] For nominal tensile strength it is permitted to use the tensile stress area of the threaded rod or bolt multi- plied by the specified minimum tensile stress of the rod or bolt material, in lieu of the tabulated values based on a nominal tensile stress area of 0.75 times the gross area. The tensile stress area shall be calculated in accordance with the applicable ASTM standard.

in accordance with the applicable ASTM standard. [c]For end-loaded connections with a fastener pattern length greater than 38 in. (950 mm), $F_{n v}$ shall be reduced to 83.3% of the tabulated values. Fastener pattern length is the maximum distance parallel to the line of force between the centerline of the bolts connecting two parts with one faying surface.
force between the centerline of the bolts connecting two parts with one laying surface. [4]For ASTM A307 bolts, the tabulated values shall be reduced by 1% for each 1/16 in. (2 mm) over five diam- eters of length in the grip.
